Add numbers without using Operator

We are providing you two ways:

1)

import java.math.*;
class AddNumbers 
{
    public static void main(String[] args) 
    {
        BigInteger num1=new BigInteger("100");
        BigInteger num2=new BigInteger("50");
        BigInteger result=num1.add(num2);
        System.out.println(result);
    }
}

2)

public class AddNumberUsingBitwiseOperators {
public static void main(String[] args) {
System.out.println("Adding 5 and 6......");
int x=5,y=6;
int xor, and, temp;
and = x & y;
xor = x ^ y; 

while(and != 0 )
{
and <<= 1; 
temp = xor ^ and;
and &= xor; 
xor = temp; 
}
System.out.println(xor);
}
}
